Features and Benefits 

  • Protocol conversion between Modbus and PROFIBUS
  • Windows utilities with innovative QuickLink function for automatic configuration within minutes
  • Redundant dual DC power inputs and relay output supported
  • Embedded data packet analyzer
  • Powerful and visual diagnostic tool
  • -40 to 75°C wide operating temperature models available



The MGate 4101-MB-PBS gateway provides a communication portal between PROFIBUS PLCs (e.g. Siemens S400 and S300 PLCs) and Modbus devices. With the QuickLink feature, I/O mapping can be accomplished within a matter of minutes. All models are protected with a rugged metallic casing, are DIN-rail mountable, and offer optional built-in optical isolation.


Windows Utilities for Easy Setup and Traffic Monitoring

The QuickLink windows utility uses a serial console port to connect to the MGate 4101-MB-PBS and makes configuration and operation as easy as possible. QuickLink can finish configuration in just few minutes by passively detecting Modbus requests with the AutoLearning function, and performing error-free I/O mapping with the AutoMapping feature. QuickLink drastically reduces Modbus-to-PROFIBUS integration time when compared to conventional I/O mapping, which can easily require days to complete.  Additionally, embedded monitoring tools can maintain logs of Modbus communication packets and assist in troubleshooting.


Redundant Power Inputs

The MGate 4101-MB-PBS has dual power inputs for greater reliability. The power inputs allow simultaneous connections to two live DC power sources, so that continuous operation is provided even if one power source fails. The higher level of reliability makes these advanced Modbus-to-PROFIBUS gateways ideal for demanding industrial applications.


Warning by Relay Output

A relay output is provided for the power input status. The relay output gives maintenance engineers an additional tool for troubleshooting and maintenance.
